Abstract

Waste management is a critical issue globally, and Bangladesh is no exception, facing significant challenges due to rapid urbanization, population growth, and inadequate infrastructure. This article explores comprehensive waste management strategies, including waste segregation, recycling, composting, and waste-to-energy technologies, emphasizing their environmental and health benefits. It examines the past and present waste management conditions in Bangladesh, highlighting the progress made and the persistent challenges. The article also compares waste management practices in neighboring countries like India, Bhutan, Sri Lanka, and Nepal, offering insights into potential improvements for Bangladesh. Emphasizing the need for public awareness, community involvement, and modern infrastructure, it calls for collaborative efforts to achieve sustainable waste management and environmental preservation in Bangladesh. This article examines the critical issue of waste management, emphasizing its importance in mitigating environmental pollution, conserving resources, and protecting public health. It provides a detailed analysis of various waste management strategies, including waste segregation, recycling, composting, and waste-to-energy technologies, highlighting their benefits and implementation challenges. Focusing on Bangladesh, the article traces the evolution of the country's waste management system, from past inadequacies to recent improvements, while acknowledging persistent issues such as rapid urbanization and insufficient infrastructure. Comparisons with waste management practices in neighboring countries like India, Bhutan, Sri Lanka, and Nepal offer valuable insights and potential strategies for Bangladesh to adopt. The article underscores the necessity of public awareness, community involvement, and robust infrastructure to achieve effective waste management. It calls for a collaborative approach involving government, private sector, NGOs, and local communities to develop sustainable solutions. By investing in modern waste management technologies and fostering responsible consumption and disposal habits, Bangladesh can address its waste management challenges, ensuring environmental preservation, public health, and overall national well-being.

Abstract

Bangladesh faces significant environmental challenges stemming from rapid industrialization, urbanization, and climate change impacts. This article examines the major environmental problems plaguing the nation, focusing on their causes, implications, and potential citizen-driven solutions. Key issues include air and water pollution exacerbated by industrial emissions and inadequate waste management systems. Rapid deforestation, driven by urban expansion and agricultural practices, threatens biodiversity and exacerbates soil erosion. The implications of these environmental problems are profound, affecting public health, food security, and socioeconomic stability. Vulnerable populations, particularly in low-lying coastal areas, face increased risks from climate-induced disasters like cyclones and flooding. Moreover, contamination of water sources with pollutants poses severe health risks, contributing to the prevalence of waterborne diseases. Addressing these challenges requires collaborative efforts involving government policies, private sector initiatives, and active citizen participation. Promoting sustainable practices, such as renewable energy adoption and efficient waste management, can mitigate environmental degradation. Additionally, empowering communities through education and awareness campaigns enhances resilience and fosters grassroots solutions. By analyzing the causes, understanding their implications, and exploring citizen-led interventions, this article provides a comprehensive overview of Bangladesh's environmental landscape and underscores the urgency of proactive measures to achieve sustainable development.

Abstract

The socioeconomic and environmental potential of cashew nut production in Bangladesh's Ranganati Hill District is examined in this study while emphasizing the crop's potential as a cash crop for rural development. With yields of 1.4 to 1.8 tons per hectare and net returns exceeding those of conventional crops, cashew farming—which was first promoted by the Department of Agricultural Extension and the Chittagong Hill Tracts Development Board—has proven very profitable. This study explores the socio-economic viability of cashew nut farming in Rangamati, Bangladesh, as a sustainable alternative for rural livelihoods. Despite advantageous agro-climatic conditions, the industry nevertheless confronts obstacles, including weak marketing infrastructure, insufficient financial facilities, and restricted availability of high-quality planting supplies. Sixty farmers participated in the research, which was carried out in eight Ranganati upazilas. It used primary and secondary data to examine the variables that affect cashew production, such as land types, seedling sources, cultivation expenses, and economic profitability. According to the findings, steep hills were the favoured land type, and 63% of farmers switched to cashew growing because it was profitable. Most farmers paid between 11.000 and 15.000 Taka a year for cultivation and obtained seedlings from the Upazila Agriculture Office (UAO). With domestic pricing between 500 and 600 BDT per kilogram and production costs between 300 and 350 BDT, cashew cultivation exhibits strong economic viability, resulting in a 95–100% profit margin. However, the sector's expansion is hampered by a lack of high-quality processing facilities and training. The research comes to the conclusion that cashew farming may greatly boost rural employment, poverty alleviation, and GDP development in Bangladesh with the right governmental support, infrastructural investment, and capacity building
